Letters Patent No.v 104,864, dated .Tune 28, 1870.

IMPRQVEMENT 1N CARPET-FASTENING.

The Schedule referred to n'these Letters Patent and making part cf the same To all 'whom it may coacernl- Beit known that l, JOHAN JKOB MRKI, of the city of Chicago, in the county of Cook, and State of Illinois, have invented certain new and useful Improvements in a Carpet-holder; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

Io enable others skilled in the art'to construct and use mylinvention, I will proceed to describe it.

My vinvention relates to'carpet-fasteners, and consists in the novel construction and arrangement of a metallic socket and pin, to be used in combination, for convenience in fastening carpets.

In the drawing, gure 1 is showing the -pin and socket. y

Figure2 is a longitudinal vertical section of the a perspective vicw,

-pin and socket on the linex :v of lig. 1, and also showing the manner of applying them; and

Figure 3 is an end view in the direction `o f the arrow, as shown in fig 1. -In constructing my carpetastener, I have sought to produce a device by which a. carpet could be easily,

quickly, and securely fastened, and, at the same time, that'vwould admit of its being conveniently released when desired. Heretofore, knobs, with a screw-pin attached, for insertion into a socket provided with a corresponding screw-thread, have been used, the socket being inserted in the door and held in position and; prevented from turning by means of screws. This-device is expensive and inconvenientin its application, and the knob is often in the way. My device is designed to be free from these objections.

I `make a metallic socket, B, of any size desired, and shaped as clearly'shown in all the gnres. Its upper Vend I make circular, and with alprojecting flange, va",as shown in the same iigures,'its body tapering, as shown in gs. 1.and2., andwithsides forming in their cross-section aspherical triangle, as shown in fig. 3, so that when inserted inthe loor it will neither work loose nor turn.' This socket I also provide with I a circular hole, b, extending through it, and make a pin, A, of corresponding shape, to the hole'l) for insertion, as clearly shown in igs.1land2, providing it with .a broad', slightly convex head, v@,asV shown in the same figures.v l

In applying my device thus constructed;I make suitable holes in the ,door and place them in the socket B, and then draw the .carpet C over -themiand insert the pins A by driving, or in any other suitable manner.

Whenever itis desired to take up the carpet," it is only necessary to draw the pins A with any convenient device-suitable for the purpose.`

The 'form of the `Asocket is such as to prevent its turning or Working loose, -While the form of the' head of the pin is such as to hold the carpet securely without injury, and is not in the way at all, and,at the same time, can be inserted and removed as desired'.

. Having thus described my invention,

What I claim is The tapering socket B, constructed in an angular form, sopthat it may be hrmly held in the door, and yet removed without inconvenience, in combination with the nail A, as herein shown and described.
